2. Blair Waldorf Yellow Coat Costume With Red Tights
Bright primary colors make this Blair Waldorf costume especially easy to recognize. Start with a black-and-white collared dress or a white blouse tucked into a dark A-line skirt. Layer a tailored yellow coat over the base, defining the waist with a slim brown belt if needed. Add opaque red tights and brown Oxford heels for Blair’s colorful school-day appearance. A structured brown satchel keeps the outfit practical while reinforcing the polished Upper East Side mood. Wear brunette hair in tidy waves and secure it with a tortoiseshell or dark red headband.

Black patent loafers keep the outfit walkable, while low Mary Jane heels provide a dressier alternative. Part dark hair to one side, curl the ends, and add a wide navy headband. Keep makeup classic with pink cheeks, brown eyeliner, mascara, and muted red lipstick. Carry a monogram-style notebook, structured handbag, and a folded city map. The costume should look intentionally styled rather than messy, so tuck every layer neatly and keep accessories symmetrical.
